Studies on Mechanical and Thermal Properties of Melamine Polyethylene Foam Reinforced Hybrid Sandwich Composites with FEA Simulation
摘要
In this study, a hybrid sandwich composites have been fabricated with expanded polyethylene foam and Melamine foam as well as Kevlar fiber as the skin material using the hand lay-up approach. The tensile, flexural and impact strength, double shear and hardness tests have been performed per the standards. As a result of the utilization of Finite Element Analysis (FEA) simulation, the prototype was being simulated for testing by its intended use. To ascertain the "thermal properties" of the hybrid composites, the thermogravimetric analysis has been performed. Results have proved that when compared to expanded polyethylene composite, the melamine foam sandwich composites have exhibited stronger strength, while hybrid composites have exhibited superior strength. Based on the tensile, flexural, impact, and inter-delamination test results, melamine foam composite appears to provide the strongest composite material in comparison to expanded polyethylene composite foam and hybrid composite foam. According to double shear and Shore-D hardness tests, hybrid composites withstand the most strain as compared to expanded polyethylene composites and POLYESTER composites. FEA simulation findings showed that the maximum deformation of 0.036244 m was attained in nodal solution due to the loading conditions on the die assembly for the melamine foam casting. There is evidence that melamine foam is more thermally stable than expanded polyethylene foam. Expanded polyethylene foam performs marginally better in terms of thermal stability when it is combined with Melamine foam. Intermolecular structures are examined by scanning electron microscopy (SEM). The foam composites could be used for aircraft cabin walls, floors, and ceiling panels where lightweight and good thermal and acoustic insulation are needed. Due to their excellent thermal resistance, these composites can serve as insulation materials in spacecraft, protecting sensitive equipment from extreme temperature variations in space. The study highlights the development of hybrid sandwich composites with improved mechanical and thermal properties, particularly with melamine foam. These composites are ideal for aerospace applications, including insulation and structural components. Advanced testing methods like FEA and SEM enhance their potential for high-performance use. These research paves the way for lightweight, durable, and thermally stable materials, especially for aerospace and defense industries.
